h(3) = -2(3)^(2) + 8(3)
-2(9) + 24
-18 + 24

Answer:

6 feet

Explanation:

A soccer ball is kicked from the ground in an arc defined by the function,


h(x) = -2x^2 + 8x

h(x) is the height of the ball and time is t.

we need to find out the height when t= 3 seconds

Plug in 3 for t


h(x) = -2x^2 + 8x


h(3) = -2(3)^2 + 8(3)


h(3) =-18+24=6

The height of the ball after 3 seconds is 6 feet.
